New Revision: 238607
URL: http://svn.freebsd.org/changeset/base/238607
Log:
Break out the TX descriptor link field into HAL methods.
The DMA FIFO chips (AR93xx and later) differ slightly to th elegacy
chips:
* The RX DMA descriptors don't have a ds_link field;
* The TX DMA descriptors have a ds_link field however at a different
offset.
This is a reimplementation based on what the reference driver and ath9k
does.
A subsequent commit will enable it in the TX and beacon paths.
Obtained from: Linux ath9k, Qualcomm Atheros
